HANDLING AND STORAGE
SDM
WARNING:
Never power up air bag system when SDM is not rigidly at-
tached to the vehicle. Otherwise, personal injury may result.
CAUTION:
After detecting one time of such collision as to meet deploy-
ment conditions, the SDM must not be used.
Refer to ªDiagnosisº when checking the SDM.

Never attempt disassembly of SDM.

When storing SDM, select a place where neither high tempera-
ture nor high humidity is anticipated and oil, water and dust are
kept off.

If SDM was dropped from a height of 90 cm (3 ft) or more or if it
is found to be damaged or deformed, replace it with a new one.

If installation part of SDM was damaged, repair that part com-
pletely before reinstallation.

All SDM and mounting bracket fasteners must be carefully
torqued and the arrow must be pointed toward the front of the ve-
hicle to ensure proper operation of the air bag system.

ALWAYS CARRY AIR BAG (INFLATOR) MODULE
WITH TRIM COVER (AIR BAG OPENING) AWAY
FROM BODY.
10B-58 AIR BAG SYSTEM
LIVE (UNDEPLOYED) AIR BAG (INFLATOR) MODULES
Special care is necessary when handling and storing a live (unde-
ployed) air bag (inflator) modules.
The rapid gas generation produced during deployment of the air
bag could cause the air bag (inflator) module, or an object in front
of the air bag (inflator) module, to be thrown through the air in the
unlikely event of an accidental deployment.
WARNING:
Never attempt to measure the resistance of the air bag (in-
flator) modules (driver and passenger). It is very dangerous
as the electric current from the tester may deploy the air
bag.

Never attempt disassembly of the air bag (inflator) modules.

If any abnormality is found, be sure to replace it with new one as
an assembly.

When an abnormality is noted as existing in the live (undeployed)
air bag (inflator) module, be sure to deploy it before discarding it.

When grease, cleaning agent, oil, water, etc., got on the air bag
(inflator) modules (driver and passenger), wipe it off immediately
with a dry cloth.

If air bag (inflator) module was dropped from a height of 90 cm (3
ft) or more, it should be replaced with a new one as an assembly.
WARNING:

For handling and storage of a live air bag (inflator) module,
select a place where the ambient temperature below 65
C
(150
F), without high humidity and away from electric
noise.

When carrying a live air bag (inflator) module, make sure
the bag opening is pointed away from you. In case of an
accidental deployment, the bag will then deploy with mini-
mal chance of injury. Never carry the air bag (inflator)
module by the wires or connector on the underside of the
module.
Otherwise, personal injury may result.

Never attempt to disassemble the seat belt pretensioners (retrac-
tor assembly).

If any abnormality is found, be sure to replace it with new one as
an assembly.

When an abnormality is noted as existing in the live (inactivated)
seat belt pretensioner, be sure to activate it before discarding it.

When grease, cleaning agent oil, water, etc., got on the seat belt
pretensioners (retractor assembly), wipe it off immediately with a
dry cloth.

If seat belt pretensioner was dropped from a height of 30 cm (1
ft) or more, it should be replaced with a new one as an assembly.
WARNING:

For handling and storage of a live seat belt pretensioner,
select a place where the ambient temperature below 65
C
(150
F), without high humidity and away from electric
noise.

Never carry the seat belt pretensioner by the wires or con-
nector on the underside of the pretensioner.

When placing a live seat belt pretensioner on the work-
bench or some place like that, be sure not to lay it with its
exhaust hole provided side facing down. It is also prohib-
ited to put something on its face with an exhaust hole or
to put a seat belt pretensioner on top of another.
Otherwise, personal injury may result.
